What facts have u given us? I havent read anything here of homosexuality being socially conditioned, except you parroting few lines prolly heard on Sundays mass.

Your notion of homosexuality being a choice is laughable. Why would anyone make that choice and make his life infinitely more difficult is beyond me, especially children which are then in a lot of cases rejected by their parents. Do u think its trending?

Take your country for example or mine, because there is a strong influence of Catholic church, which is meddling in politics, education, etc... What kind of benefits would gays have in this surrounding, when their basic rights are trampled on a daily basis? I have never even heard of someone coming out and saying: "Yes, I was a straight heterosexual male few years ago and then I switched sides. The best decision Ive ever made".
The only decision that can be made concerning this is to come out, when that person is ready, because there is still a lot of stigma around it.
